Impressive balancing ! At start there seem to be no way to survive, but you eventually find the right combination of trees, and after a while, you gain these extra seeds that change everything and your effort finally paid off: you can smash your msb and fill these island with hundreds of trees.. feels really good !

Cool Concept, Spent the first few min planting trees on land then i found out you can plant them in the water. This made me unnaturally happy.  Would love to see more control over how the trees work. Like upgrading them with seeds to last longer or produce more resources. 

Well done on your first game, I am impressed.  Resource management is a cool take on the theme and you did a good job making that sort of system. Seeing the costs of the trees would have been nice and having bonuses for placing certain ones next to parts of the landscape would be a way to put more of the focus on building a forest rather than just arbitrarily placing a tree. Well done.
